Fulford: AdBlue in the Diesel Tank? Leave It Off

AdBlue in the diesel tank? Then leave your motor off — and the ignition as well. Urea mixed in water is all AdBlue is. It does not burn, it doesn't mix with diesel, and the harm it does starts when the fuel system pulls it in. A drain and a thorough flush, done where the car is in Fulford, is normally what AdBlue in a diesel tank takes — if it's caught before your engine has been run. Nothing comes before ringing 0333 366 0103.

Fulford, AdBlue in your diesel tank: what to do right away

Do:

  • Keys out — that way no one can switch anything on.
  • Hazards on, if moving traffic is at all near.
  • Which product, and roughly how much amount? Save the bottle or the receipt, and our technicians can know.
  • Tell us a postcode starting ST11 9, or whatever street lies nearest, and our van reaches you directly — so call wherever you are.

Things not to do:

  • Moving the car even a short way is no reason to start your engine.
  • Plenty of diesels run their pump the moment your ignition comes on, so keep it off.
  • AdBlue doesn't mix in diesel — it separates out — so adding more diesel will not thin it.
  • Any driving at all is best avoided, including a short way up The Green.
  • No emptying it yourself, at all, on the verge.

The attendants working at any Fulford forecourt — the JRM among them — will usually help pushing it clear if you ask. Stopped on your own driveway? Then it remains exactly as it is.

AdBlue in a diesel tank: what it does

Not the engine but your exhaust is where AdBlue belongs. Kept in a dedicated tank, it is squirted into the exhaust to clean the fumes. Nothing in a fuel pump is designed for this fluid — and no part of that was meant to travel through one.

Tipped in with your diesel, it keeps separate rather than mixing — entirely different from fuel. Heavier than diesel, it sinks and pools underneath it — the very place the intake sucks from. The first thing the fuel system pulls through, once it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Spot Acre last night, and hasn't been started since, is still the simple case: the AdBlue is lying at the bottom of the tank, and nothing has drawn it in.

Two kinds of harm come from there. Crystals and corrosion. As the water evaporates, it strands urea that crystallises in filter elements and narrow passages; and, because it eats at some metals, each part it touches suffers for as long as it stays in there. A car left standing in Fulford with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. Water protects nothing. The high-pressure pump and every injector need diesel flowing through them, and so the water part harms them in its own right.

Draining AdBlue from a diesel tank in Fulford

AdBlue in a diesel: why it is regularly worse than petrol

Put petrol in a diesel at the another forecourt nearby and you have an issue of thin fuel. No harm is done as long as it stays put, mixed into the diesel — only when the motor runs on it.

AdBlue in a diesel is a fault of the wrong substance altogether. It does not burn, so it cannot simply be run through. Whether the car is in Saverley Green or the centre of Fulford, turning it over "to see" does more harm in this case than almost any other error, and the flush counts more. The reasons: it won't stay blended, and so watering it down is impossible; and deposits and corrosion outlast the next fill.

The good news is the same as with petrol. Anywhere across Staffordshire the car has come to rest, an unrun motor means the AdBlue still in the reservoir: the simplest part of a fuel system to empty.

How AdBlue ends up in a diesel tank around Fulford

After dark, two caps together — the AdBlue cap and the diesel cap, now and then behind a single flap — may look the same. Nobody means it; plenty of designs invite it. Most of the time it happens with a bottle bought on the way home and poured in on the driveway, not at the pump.

Usually, it happens in one of a few familiar ways. Rushing, outside Fulford Primary School, after a warning light flashed on during the school run, someone refills the car. A bottle is poured in at the end of the day on a drive just off Townend. Another version: darkness, the car park outside The Shoulder of Mutton, and someone opening that flap the first time.

It takes place most in the vehicles people know least: a hire car, a new vehicle, a company car, or the second car of a household with one diesel and one petrol. Wherever around Staffordshire, Fulford included, the mistake does not change, and neither does the first response: keep it switched off.

AdBlue in the diesel tank in Fulford, and your engine started?

In that case, the AdBlue is no longer in the tank. It has been sucked through the filter and the fuel lines, and if your engine ran for any time, it has got to your high-pressure pump and your injectors.

Perhaps returning from Schoolhouse Wood, or part way across Fulford, your motor might go lumpy, smoke, drop pace, flash your dash or stall. Once you safely can, pull over then switch it off — without restarting to test. More of that is pulled through with each start.

Exit the M6, under 10 miles from Fulford, by the first junction and park somewhere safe, not carrying on.

Each mile pushes the AdBlue deeper into your system. That is why crossing Fulford to park beside Fulford Village Hall and a drive of under 10 miles for Stoke-on-Trent are such separate jobs. Roughly how far had it come? Tell us.

Once the engine has run, the flush covers more, and all of it is done where the vehicle has stopped. Very rarely does it leave long-term damage when it's caught soon.

What does an AdBlue drain on a diesel involve around Fulford?

A road by St Nicholas Church Fulford, a drive, a lay-by or a forecourt: anywhere your vehicle has come to rest in Fulford, our technicians travel to it. The job depends on three replies, and our technicians get before all else — which fluid was put in, the amount, and if the motor has turned over.

Next, emptying the tank on the spot removes the contaminated diesel along with the AdBlue in one go. A full flush matters far more with AdBlue than with petrol, because what remains won't wash out on its own. Next, your filter: flushed, or changed when it must be. After that clean diesel, then a test of the vehicle. The majority of these jobs are a half-hour visit once we arrive, if the engine hasn't run. The pumping gear is explosion-proof, so a busy forecourt is no problem, and it's quiet enough for a residential street late at night.

Last, the system is bled with new diesel. You head off as soon as our technicians have started it, and it makes no difference whether the vehicle is on a drive in Fulford or in a space outside Blythe Bridge. Before leaving, our technicians check it is running correctly with new diesel in. Since the job is done in its entirety where the vehicle is, a workshop never comes into it. Your insurer will want an engineer's report and the VAT invoice — each handed over once the job is done.

Fulford has a population of around 655 residents and is located about 128 miles northwest of London.

AdBlue drains across Fulford and Staffordshire

Crossgate, Mossgate and Mosslane are among the places around Fulford that the same vans reach, along with much of Staffordshire beyond, over the ST postcode area. Near a border, or somewhere tricky to pin down? Asking is better than guessing, so phone.

A van that comes to you fits Fulford, a rural village: you have no need to take the car to us, because we drain it there, on a driveway, a residential street, a parking area or a filling station.

AdBlue in a diesel tank around Fulford: the cost of fixing it

Because the callouts vary, a single price would not be fair. The cost changes first with how long, if at all, the motor has been running, and next with the amount of AdBlue that got in. After that it turns on where the vehicle is and whether our van can reach it safely, which is simpler on an open driveway than in a tight space behind St Mary.

That's why each call from Fulford starts with the same three questions, asked before giving a figure, not after: what got in, how much, and if it has run. With them, a range shrinks to one firm number.

Quoted by phone before the van sets out, the job is settled that day — card or phone, nothing in advance. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way.

In Fulford and still next to the vehicle?

Then the most helpful thing you can do is nothing to your car. Keys out, engine off, ignition off. Ring 0333 366 0103 and tell us it's AdBlue, about how much, and whether it has run. Petrol in Diesel takes it from there, in Fulford or anywhere in Staffordshire.
